HTTP Headers & Methods - Rest APIs In Depth

Let's take a look at HTTP Headers together and look at some practical examples in Insomnia and Deno.

We start with an overview of what HTTP Headers are as well as some visuals and examples using both Chrome and Insomnia to inspect them.

Then, we look at the different HTTP Methods such as GET, POST, PUT/PATCH, DELETE as well as the less known ones such as HEAD and OPTIONS.

We then look at the HTTP Response Status Codes, what they mean and when we might use them to prepare for building our own REST APIs.
